' IRONING STEAM; PRESS.

Applicationflled une 1a, 1927," ser al No 199,852, and in am. October14, 1826.

This invention relates to steam presses for ironing clothes and otherarticles, and it refers more particularly to the method of suspensionand'the construction of'themovable-upper plate of the press.

The upper plate, in a steam ress, is

j generally connectedto its supporting arm by an articulated jointgiving it the necessary freedom of movement for compensating theinequalities of thickness of the material of the clothing or garment,and the consequent inequalities of pressure at different points of thesurface of the plate.

- One method of suspending the plate consists in the use ofspringscombined with V- shaped ribs orknives provided either on the supportinarm or on the plate, and deter-' mining beween the said two members,lines of support extending at right angles to the longitudinal axis ofthe plate, about which lines the said plate can swing within the limitpermitted by the springs. This means is however insuflicient forensuring uniform distribution of pressure throughout the wholev surfaceof the plate, as though it allows of a swin ing of the plate inlongitudinal direction, it does not possess suflicient flexibility toallow also of a swinging in the transverse direction. An excessiveunequal pressure on the plate is liable therefore to produce itsfracture.

One object of-this invention is to remedy the said drawback and itconsists, whilst retaining the well "known principle of spring sphericalhead orits e uivalent, en'a Suspensiomindoing away with the supporting Vshaped ribs and in replacing them by a central pivot s'uch as a ball, a

ling th plate. to move in any irection and therefor bringing aboutequalization .of pressure throughout the, whole extent of the surfa a ofthe plate.

The risk of fracture of the plate thus be-Q ing decreased it becomespossible to. make it lighter an more particularly to reduce body asystem of ribs or bafiies which cause the steam or other heating fluidto follow a rational path across the plate.

Another object of the invention relates to 1pm .with

cally' wound metal bands which will allow leakage of steam, are made ofa single piece of metal, and the tubes are so shaped as to havecorrugations in the direction of the longitudinal section of the tubes,which corrugations impart to the tubes the desired flexibility and avoidany leakage of steam.

In the accompanying drawing:

Fig. 1 is a side elevation, with sections, of an ironinfg press providedwith the improvements re erred to;

Figs. 2 and 3 are a vertical section and a plan of the suspension of theupper plate;

Fig. 4 is a partial front elevation of the press, partly in section,

Fig. 5 shows'the body of the plate in plan.

In said figures, a1 is the supporting arm terminatin in the plate-holderb to which is attache theu per plate 0. According to the invention, t efixing of the plate a to the plate holder 1) comprises several angleirons d and a certain number of suspensionsprings e with central guiderods f which rest on a flange portion of the p ate 0 which is situatedbelow the holder b is recessed as indicated at h, and in the center ofthe recess is arran ed a boss 5 with a small spherical seat in whlch ismounted a ball 10, generally of steel, in-

terposed between the said boss z and the plate holder 6. v B vreasonofthis ball as well as theirecess .w ich e xtends under the whole surfaceof he plateholder, the press plate can swing in any direction,longitudinally as well as of the plate holder. The

transversely, and adapt itself to an inequal- 1 to be pressed. In orderto prevent the plate from' rotating about'its pivot, there is pro--ities of thickness of the article 0 clothing tem of. rigid pipes witharticulated steam than that of tubes formed of spiral bands,

and the tubes thus made are not liable to allow leakage of steam at anypoint of their length. The use of these tubes improves the conditions ofworking with the press.

with reference more particularly to Figures 4 and 5, the plate which aswill be seen is of a reduced thickness, is made in two pieces, that isto say the body p forming the heating chamber, is made independentlyofthe cover plate already designated by the letter 0. This constructionmakes it possible to cast the ribs or baflles 1', s, t which force theheating fluid, steam or other, to pass right through the chamber betweenthe inlet a and the outlet 0.

What I claim is:

1. In an ironing steam press, a movable arm pivotally connected with theframe of the press, a flanged plate holder at the outer end of the armfor supporting the upper plate of the press, and a ball joint connectionbetween the plate holder and the upper plate of the press consisting ofa ball seat at the the plate holder, and means for movably Y attachingthe plate of the press to the flanged plate holder. i

2. In an ironin steampress, a movable arm connected wit the frame of thepress, a flanged plate holder for supporting the upper plate of thepress, an upper plate for the press, a ball joint between the plate andits plate holder, and means for movably attaching the upper plate of thepress to the flanged plate holder, consisting of brackets extendingupwards from the upper face of the plate close to the flanged plateholder, guide rods on the brackets and suspension springs around theguide rods hearing at one end against the brackets and at the op-vposite end against the flanges of the flanged plate holder.

3. In an ironing steam press having a ball joint connection between theupper plate of the press and the plate holder, means for preventing theplate from rotating about said ball joint connection, consisting of arecessed central part in the upper face of the plate, a groove openinginto the recessed central part, a plate holder extending into therecessed central part of the plate, and a finger attached to the lowerface of the plate holder, said finger engaging the groove which opensinto the central recessed part of the plate to prevent the rotation ofthe plate.
